Subject: [GIT PULL 0/6] More EFI updates for v5.7

Hello Ingo, Thomas,

A small set of EFI followup changes for v5.7. The last one fixes a boot
regression in linux-next on x86 machines booting without EFI but with
the IMA security subsystem enabled, which is why I am sending out the
next batch a bit earlier than intended.

Thanks,
Ard.

  efi: mark all EFI runtime services as unsupported on non-EFI boot (2020-02-28 12:54:46 +0100)

----------------------------------------------------------------
More EFI updates for v5.7

A couple of followup fixes for the EFI changes queued for v5.7:
- a fix for a boot regression on x86 booting without UEFI
- memory encryption fixes for x86, so that the TPM tables and the RNG
  config table created by the stub are correctly identified as living
  in unencrypted memory
- style tweak from Heinrich
- followup to the ARM EFI entry code simplifications to ensure that we
  don't rely on EFI_LOADER_DATA memory being RWX
